Questions & Answers

1 Question • 1 Answer

"Will not clear stud girdles." What are the implications of this. Could damage to something result? Does it prevent the installation of the valve cover if some modification is not made. If so what would be the correct procedure to fit and use this product with the best possible outcome? In case you didn't guess by now, I'm not familiar with this motor, a '92 Chevy 305, having just gotten my first today, and I'm not completely sure what a "stud girdle" is.
